I wonder what an Aquaduck story would be like (he saw some action in both segments of this Zoo Crew storyline, but...). Presumably, Black Manta is an actual manta... would his half-brother be the villain "Ocean Mallard"? :-)

Re: Hawkwoman: since Earth-C-Minus was supposed to reflect whatever the current state of Earth-1/the DCU was, I'd assume there is a Hawkwoman analog ("Hawkwombat"?) somewhere. Though can only imagine what Earth-C-Minus must be like these days (reboot-central too?).
